Michael Eligon, a mentally ill 29-year-old man armed with two pairs of scissors, died of gunshot wound sustained in a February confrontation with police. Critics accused police of using excessive force

The province’s Special Investigations Unit is facing fresh criticism after a French TV documentary raised questions about its handling of a high-profile police shooting.

Michael Eligon, a mentally ill 29-year-old man armed with two pairs of scissors, died of a gunshot wound sustained in a February confrontation with police. Critics accused police of using excessive force in the case, but a subsequent SIU investigation cleared the officer who fired the fatal bullet of any wrongdoing.

In the French documentary, one of the SIU investigators can be seen wearing what appears to be a police ring.

“We have a policy in place that clearly states investigators are not to wear police insignia, as it could give the appearance of pro-police bias,” SIU director Ian Scott said in a statement to the Canadian Press on Friday, calling the incident a “very serious transgression.”

The SIU says it has suspended the investigator and disciplined two others over comments that suggested a bias.
